This article will help you quickly take a Raspberry Pi and configure it as an Internet Router.

We focus on OpenWrt 21.02.3 software and Thales IoT 5G, 4G, and 3G Cellular module hardware MV31-W.
Note that only the newest Raspberry Pi 4 and above will offer true multi-100Mb/s throughput.

Internet connectivity is achieved using the high-performance Mobile Broadband Interface Model (MBIM) method. We use the libmbim command line utilities to drive the module (not AT Commands).
